CORNBPLANTER AND 'CHECKQROWER.

SP3 CIPICATIGN' '31 Application filed May 3, 1887. Serial No. 236,9C0.(N'o model.)

To all whom it may concern:

Be it known that we, JOHN \VESLEY OMA- HAN and EDWIN STANTONWHrr'rEMoRE, both of Huntingdale, in the county of Henry and State ofMissouri, have invented a new and Improved Corn-Planter and Check-Bower,of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improvedcorn-planter and checkrower which is simple and durable in constructionand very effective in operation.

The invention consists in the construction and arrangement of variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of our improvement, parts being in section. Fig.2 is a sectional side elevation of the same on the line as a: of Fig. 1.Fig. 3 is a vertical crosssectional elevation of part of our improvementon the line 3 y of Fig. 1. Fig. 4 is a sectional end elevation of partof our improvement on the line 2 5, Fig. 1. Fig. 5 is a sectional sideelevation of the same on the line 20 w of Fig. 4. Fig. 6 is a sectionalend elevation of the seed-box frames on the line a a of Fig. 2, and Fig.7 is a plan view of one end of the seed-box frame with the seed-boxremoved.

On the suitably-constructed frame A is so cured the axle or shaft B, onthe ends of which are mounted loosely the driving-wheels G and O, ofwhich the driving-wheel O is provided on itsinnerhub withaclutch-wheel,D,adapted 0 to engage a clutch-wheel, E, formed on the hubof the cam-wheel F, mounted loosely on the part B of the axle B. Thecam-wheel F is provided with three projections, F, in its rim, adaptedto engage alternately the frictionroller G, mounted on one end of thelever G, fulerumed on the main frame A, and engaging with its other endthe slotted arm H, secured to the bar H, adapted to slide sidewise ontop of the seed-box frame 1', pivotally connected with the main frame A.

The two ends H of the sliding bar H are reduced and slide in suitablegrooves formed in the bottom of the seed-boxes K, of suitable size, andheld on the outer ends of the seedboX frame I. In the center of thebottom of each seed-box K is pivoted a slide, L, provided with a slotnearits outer end, which engages a pin, H, secured to the top of thereduced part H of the sliding bar 11. In each of the slides L is alsoformed an aperture, L, adapted to register with a vertical slot, J,formed in the rear end of the plow J, secured to the outerend of theseedbox frame Ldireetly below the seedbox K. In the slot J is pivotedthe lever N, forked at its upper end,and engaging with this end the pinH, secured to the inside of the reduced part H of the sliding bar H.

The lever N is so arranged in the slot J that when its upper end is onone side of the slot J then the lower end of thelevcr is at the oppositeside of the slot, and when the bar H moves sidewise then the relativepositions of the upper and lower ends of the lever N are correspondinglychanged from one side of the slot to the other. The sidewise motion ofthe bar H also imparts a swinging motion to the slides L by means of thepin H so that the apertures L open into the slots J and deliver grain tosaid slots from the seed-boxes K. Near the middle of the sliding bar H,and extending downward, is secured a toothed rack. O, meshing into thesegmental teeth 0, formed on the upper end of the lever O, fulcrumed onthe seed-box frame I and extending downward, being pointed at its lowerend,which is adapted to mark in line with the respective hills intowhich the grain has been dropped when the levers N were actuated by thesliding bar H.

On the inside of the camwhcel F is formed a hub, F grooved at its rim,which is engaged on its upper side by a semicircularly-grooved rimformed on the disk P, mounted loosely on the part B of the shaft B.Against the outer face of the disk P presses one end of the spring P,coiled on said part B of the shaft B, and 95 resting with its other endagainst the shoulder formed on the shaft B. This spring P has atendencyto press the clutch E ofthecam-wheel F into contact with theclutch D of the-main driving-wheel G. From the face of the disk Pproject inward two arms, P pivotally connected by the links Q, with theforked end of the lever It, extending upward and being fulcrumed on themain frame A.

The operation is as follows: The operator occupying the seat S, securedto the main frame A, can move the cam-wheel F in and out of contact withthe main driving-wheel C by moving the forked leverRsidewise,so that thelinks Q impart a sliding motion to the disk P,which,

by its semicireularly-grooved rim, moves the cam-wheel F sidewise on thepart B of the shaft B. When the cam-wheel F is in clutchcontact with themain driving-wheel O, and the frameis moved forward in the direction ofthe arrow at, then the main drivingwheel O imparts a rotary motion tothe cam-wheel F, whieh,by its projections F, imparts a sliding motion tothe bar H by means of the lever G. As the cam-wheel Fis provided withthree projections F, it will be seen that for every revolution of themain driving-wheel C said camwheel F imparts a sliding motion to the barH three times. The sidewise-sliding motion of the bar H imparts aswinging motion to the slides L by means of-the pins H and at the sametime the bar H imparts a rocking motion, by means of the pins H", to thelevers N in'the slots J of the plows J. The levers N stand parallel toeach other, and in such a relative position at their upper ends to theapertures L that the latter drop, on their swinging motion, corn intothe slots J at every sidewise motion ofthe sliding bar H. The graindropped into the slots J is retained in the same by the levers N, and isonly delivered to the ground at the next shifting motion of the-leversN, imparted to the same by the sliding bar H. Then the grain passed fromthe seed-boxes into the slots J by means of the slides Lis retained insaid slots J until the next sidewise motion of the levers N, and thenthe grain in both slots is dropped simultaneously into the furrowsformed by the front end of the \plows J. At the same time that thistakes place the bar H imparts, by its rack 0, an oscillating motion tothe lever 0, so that the latter forms with its pointedlower end a smallfurrow in the ground between the two hills in which the grain had beendropped, as above described.

' If the operator desires to interrupt the sliding motion of the bar H,thus preventing the seed from dropping into the furrows, he moves theupper end of the lever R outward, whereby the links Q, pull onthe diskP, which, by its semicircularlygrooved rim, pulls the camwheel F inward,whereby the clutch E is disengaged from the clutch D of the maindriving-wheel G, and the latter rotates without rotating the cam-WheelF. It will be seen that at the moment the grain is dropped into thefurrow from the two seed-boxes K the hills in which the seed has beendropped are marked by the scraping-lever O.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- The combination, with the frame, thedrivewheels, axle, grooved cam-wheel F thereon, provided within thegroove with the three projections F, and a clutch mechanism for saidcam-wheel,of the horizontally-oscillating lever G, entering the grooveof the cam-wheel at its rear end, the transversely-movableslide-operating bar, the pivoted seed-slides L, operated by said "bar,the pivoted levers N in the seedspouts and operated'by said bar, therack O "on the bar, and the vertical pivoted marker 0, having teeth onits, upper end engaging said rack, substantially as set forth.
